Arctic vegetation is largely controlled by the mean temperature in July, the warmest month. Arctic vegetation occurs in the tundra climate, where trees cannot grow.Tundra climate has two boundaries: the snow line, where permanent year-round snow and ice are on the ground, and the tree line, where the climate becomes warm enough for trees to grow. [7]
Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline.
Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest ) and tundra . [ 2 ]

The underlying soil of this damp Arctic coast is thick, solid permafrost, covered in summer with thermokarst "thaw lakes" of melted ice. Ice features such as ice wedges and pingo mounds of soil and ice can be found. This coast has an arctic climate warm enough to allow plant growth in late-June, July and August only, and even then frosts may occur.
Rubus arcticus, the Arctic bramble [4] or Arctic raspberry, [5] [6] Nagoonberry, [7] or nectarberry [8] [9] is a species of slow-growing bramble belonging to the rose family, found in Arctic and alpine regions in the Northern Hemisphere. It has been used to create hybrid cultivated raspberries, the so-called nectar raspberries. [9]
The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. [3] Arctic land is bordered by the subarctic.
Frost action processes have a strong effect on the soil and vegetation of arctic-alpine regions. [5] Tropical alpine regions are subject to these conditions as well, but they seldom happen. Because northern alpine areas cover a massive area it can be difficult to generalize the characteristics that define the ecology. [ 6 ]
